[vtkusers] how to query all available shader variables of a loaded material

[Fangerau Markus]

Hello,

 

In our application the user can apply shaders on a surface by selecting
an xml material from a drop-down box.

But I also want the user to be able to edit the specific shader uniforms
(variables)

 

My question is now:

 

Is there a clean/future-proof way to query all available shader variable
names and their types

from a vtkProperty that has a material w/shader loaded?

 

The only solution I found was manually parsing the xml file,

or maybe by traversing the associated vtkXMLMaterial.

But I am worried about future changes/extensions to the vtk XML Material
format.

 

Thanks in advance,

Markus
